Pulmonary Embolism Severity Index (PESI)
Study by Aujesky helps us to predict the 30 day mortality risk in patients with PE. Below are the two tables which gives the risk severity, and second table helps to give the assigned points on the basis of risk factors.
Category = Points = Risk category
1 = less than or equal to 65 = Very Low
2 = 66-85 = Low
3 = 86-105 = Intermediate
4 = 106-125 = High
5 = more than 125 = Very High
Predictors and Assigned Points
Age/year = Age in years
Male Sex = +10
Hx Cancer = +30
Heart Failure = +10
Chronic lung disease = +10
Pulse more than 110/min = +20
SBP less than100 mm hg = +30
Resp Rate more than 30/min = +20
Temp less than 36ºC = +20
Altered mental status = +60
O2 Sat less than 90% = +20
